I thought it was ok if they are pasteurised but to avoid brie, camembert, blue cheese as the bacteria that is used in these can cause probs. I just looked on the
Food safey website and this is what they say about cheese.
"Dairy products
Dairy products (milk, cheese, butter, yoghurt) are important sources of protein and calcium in pregnancy and their consumption is encouraged. Commercially produced New Zealand and imported dairy products are pasteurised and this kills any pathogens in the raw product. However, after opening these products, there is potential for contamination by pathogens that may lead to illness. Listeria can grow at refrigeration temperature to numbers that can result in an infection. For this reason, dairy products should be kept well covered to prevent contamination. They should ideally be consumed within two days of opening, or used in cooked foods after that two-day period. All soft cheeses (including brie, camembert, blue, ricotta, mozzarella) should be purchased in small quantities and eaten immediately after opening the sealed pack. Pregnant women should not eat leftover soft cheeses.
Raw milk and raw milk products (such as unpasteurised milk drunk on the farm and home-made cheeses made from unpasteurised farm milk) should be avoided."
